Autodesk AutoCAD Map 3D Object Data Writer Feature Type Parameters

To access feature type parameters, click the gear icon on a feature type in the workspace to open the Feature Type Parameter Editor. To always display the editor in Workbench, you can select View > Windows > Parameter Editor.

All feature types share similar General Parameters. This includes Name and Writer Name. From here, you can also control Dynamic Properties.

In the AutoCAD Map 3D Object Data Writer, definition lines without user attributes are treated as layer definitions, while any definition lines with user attributes are treated as object data table definitions where each attribute will become a column.

Not only does the AutoCAD Map 3D Object Data Writer require that every feature written to the AutoCAD DWG/DXF file be stored within a defined layer, all object data information must be stored within a defined object data table. In AutoCAD DWG/DXF drawings, the layers are used to store collections of logically related attributes, and the object data tables are used to associate additional information with the entities stored on those layers.

Within FME, layers and object data tables are both made from FME feature types. An FME feature with a feature type that defines an object data table may write both entity and object data information to the output file, and may dynamically create a layer for the entity information if necessary. An FME feature with a feature type that defines a layer will only write entity information to the output file.
